http://lightzoneproject.org/node/2/This is a free source program that divides photo areas based on intensity of light. Allows correction.
" LightZone also offers some unusual tools for tonal control — meaning brightness, contrast, shadows, highlights, etc. Some are inspired by the Zone System, and some are inspired by HDR tone-mapping. These tools put LightZone in a class by itself for working with black-and-white imagery. They're very useful for color photos, too, especially in mixed lighting situations. "
